Images that are brought into AutoCAD® must have the rectangular frame around it displayed if you want to modify the image. Since you usually do not want the rectangle to print, you turn it off. The IMAGEFRAME variable that controls image frame visibility now has three options. A setting of 0 turns off the rectangle so that it does not print. A setting of 1 displays the rectangle and prints it. A great new setting of 2 displays the rectangle so you can manipulate the image, but does not print the rectangle. This is also on the Reference panel of the Insert menu.

There is a hidden (undocumented) benchmark program installed with every AutoCAD (and AutoCAD based program). You can use it to check the graphics performance of your PC.

The benchmark program comes in the GsTest.arx program file (in the AutoCAD folder). To run this benchmark, first load the ARX application (e.g. with the APPLOAD command) and then start it with the GSTESTBENCHMARK command (type it).

The Autodesk® Subscription Advantage Pack for AutoCAD® 2010 includes a new set of TimeSaver Tools to help you work faster. You can now more easily select and work with objects when editing drawings to help streamline project workflow. Several TimeSaver Tools were top AUGI wish-list requests.

New TimeSaver Tools features include:

1. Hide and isolate objects—Turn objects on and off regardless of layer to save time in tracking objects across layers and quickly show or hide objects as needed.
2.Select similar—Select objects with similar properties, such as layer or linetype, or blocks and xrefs with the same name.
3.Create selected—Create a new object for your drawing by matching the type and properties of another selected object.
Hatch to back—Streamline the process of working with hatches by easily selecting hatches and 4. then sending them to the back of the drawing.

Customers with a current subscription contract can download the bonus pack through the subscription centre.
